Neglecting energy absorbed or reflected by our atomosphere, the solar energy hitting 1 sq. meter of Earth's

Question

surface is 1360J/s (the solar constant). How long does it take a baseball diamond (90 ft on a side) to receive 1 megaton of solar energy?

Answer 1

What luck! I just saw in another question a statement that a megaton was equivalent to 4X10^15 joules. If that is correct then:
Diamond area 90 feet square is 752 square meters.
752*1360=1,022,720 joules per second
4X10^15/1,022,720 = 3,911,138,924 seconds or 124 years

That would be in space, it would take longer on the ground. At least twice as long just because of half the time being at night, and more because the Sun is not always directly overhead and clouds and so on.
